Title: Apparatus for determining home position in serial printer
Inventor: TANAKA HIROTOMO
IPC: B41J19/18
Filed: 1994-07-15
Abstract: PURPOSE:To reduce the cost of an apparatus for determining the home position of a recording head in a serial printer without the need for a home position detecting means by detecting that a pulse signal output from a position detecting means for the recording head is not varied for a longer period of time than the ordinarily running time of a carriage, and stopping the carriage in a state that it abuts against a damper member. CONSTITUTION:When a power source switch is closed, a pulse motor 5 is driven by a carriage controlling means 10, and a carriage 1 is moved toward a home position. At that time, an output signal of an encoder 8 is inputted into a home position setting unit 11. When the carriage 1 abuts against a damper member 9 located at the home position, the movement of the carriage 1 is checked, and the signal from the code board detector 8 becomes unvaried. Thereupon, when an abutment detecting means 12 detects that the signal from the code board detector 8 is not varied for a predetermined period of time, driving energy supplied to the motor 5 is gradually reduced by a brake driving means 13, and the positioning of a recording head 2 is determined in the home position.

Abstract: PURPOSE:To easily produce a soft magnetic iron sheet for a magnetic shield excellent in magnetic characteristic by hot-working, heat-treating and then annealing a steel slab consisting of C, Si, Mn, P, S, Al and Fe in the specified manner. CONSTITUTION:A steel consisting of <=0.02wt.% C, <=0.30% Si, <=0.50% Mn, <=0.10% P, <=0.01% S, 0.10-0.50% Al and the balance Fe and inevitable impurities is melted and refined into a slab. The slab is heated above the AC3 point and then hot-worked, e.g. rolled. The hot working is finished with the draft in the ferrite region below the AC3 point controlled to >=20% to increase the crystal grain distortion. The steel sheet is then heated above 850 deg.C, held at >=t/25.4X60min (t: sheet thickness), cooled to at least 700 deg.C to grow the crystal grain and then allowed to cool in the atmosphere. Consequently, a soft magnetic iron sheet having the coarse grain smaller than the ferrite grain size 1, >=20,000 maximum magnetic permeability mumax and >=1.0T magnetic flux density at 1.0Oe magnetic field is obtained.

Abstract: PURPOSE:To attain the constitution only with a digital element by forming an oscillator to oscillate at a high frequency in the internal part of an LSI, and executing the multiplying action only with a digital processing circuit to use a reference clock signal obtained by the oscillation. CONSTITUTION:By an oscillating circuit 1, a reference clock signal 21 of a frequency higher than an input clock signal 20 is oscillated, when the input clock signal 20 is at one side level, a counter 4 counts the reference clock signal 21, and each time the input clock signal 20 is changed to other side level, the counted value of the counter 4 is divided by a dividing circuit 5 and the result is held at a register 6. On the other hand, an initial value is '1', a counter 7 counts the reference clock signal 21, and a comparator 8 outputs a signal 32 when the counted value of the counter 7 is larger than the contents of the register 6. Thus, the multiplying can be executed in the internal part of a digital exclusive-use LSI.

Filed: 1986-08-13
Abstract: PURPOSE:To prevent the misinput caused by the change of the writing pressure of an input pen by adding a gate circuit to a time counting circuit to detect the peak value of the wave detected first out of the detected voltage. CONSTITUTION:A counter circuit 6 is set at '0' when a start signal is supplied and at the same time an elastic wave is outputted from a pen. This elastic wave is detected by a detecting element via an input plate and converted into digital signals by a zero-cross circuit 1 to be used as a DO signal. In this case, A and B signals are produced by gate A and B circuits 4 and 5 respectively. The A signal shows the time needed for the rise edge of the detected wave and produces a C' signal via an AND circuit C to a CK signal. While the B signal produces a D' signal via an AND circuit D to the output of a 1/2 clock circuit 3. The sum of both C' and D' signals show the peak point of the detected waveform. Thus, an OR circuit E is provided and the E' signals of the circuit E can be counted by the circuit 6.
